Genuinely offline

Your photos never leave the phone

Conversion never touches the internet. Images are decoded, rotated and written into the PDF entirely on your device. There is no account, no sign-up, no cloud storage and no server behind this app — it works on a plane, in a basement, on a train.

No upload, everYour images and PDFs stay on your device.
No accountNothing to sign up for, nothing to sign in to.
Only your selectionThe Android photo picker shares just the images you choose, not your gallery.
Internet for ads onlyNever to transmit your files.

What Foldra does

Everything between your camera roll and a finished PDF

Convert

Merge photos into one document

  • JPG, JPEG, PNG, WebP and HEIC images
  • Combine any number of images into one multi-page PDF
  • Receipts, screenshots, scanned pages, whiteboards, handwritten notes
Foldra home screen — pick images and combine them into a single PDF offline

Arrange

Fix the order before you convert

  • Long-press any page to drag it into a new position
  • Rotate the pages that came out sideways
  • Remove pages, or add more without starting over
Foldra arrange screen — reorder, rotate and remove pages before converting

Control

Decide how the PDF comes out

  • A4, Letter, or fit the page exactly to your image
  • Orientation and margins to match what you are sending
  • A JPEG quality slider — trade sharpness against file size
Foldra options — A4, Letter or fit-to-image page size, orientation, margins and JPEG quality

Share

Open it, send it, or file it away

  • Open the PDF straight away in any reader
  • Share to email, WhatsApp, Drive or anywhere else
  • Save to Downloads, or choose exactly where it goes
Foldra result screen — open, share or save a finished PDF with no watermark

Pricing

Free to convert. Ad-free for a one-time price.

The conversion feature is free and stays free — no watermark, no page limit, no trial that expires.

  • Free — no subscription, no sign-up
  • No watermark and no cap on pages
  • A one-time in-app purchase removes ads permanently

The free version shows ads from Google AdMob, which is the only reason the app requests internet access.
